Saves are immensely important. The point is, Papelbon was the link holding the sox staff together last yr. Late in the game, sox had a small lead, who comes in? Paps!
Sox are tied late in a game, who comes in? Paps!
Sox are down 1 late in a game, who comes in? Paps!
He was the setup man, closer, reliever to keep it close, and reliever until the sox won the game. He filled tons of roles and pitched too many innings, especially late. If the sox stick to their "guidelines" then Paps is pitching 50 innings this yr. Who takes the other 25+ when the game is on the line? And note, those 25 innings are typically 25 1-inning stints. You better hope Donnelly stops the slide.
